Abstract Background Minimal access surgery is associated with improved cosmetic and other short-term outcomes. Conventionally, an abdominal incision is made for specimen extraction. We assessed the feasibility of specimen extraction through one of the natural orifices and analyzed its impact on short-term outcomes. Methods A prospectively collected data were reviewed on consecutive patients who underwent natural orifice specimen extraction (NOSE) after laparoscopic colorectal surgery. The results were compared with a matched group who had transabdominal extraction (TAE) of the specimens. A systematic literature review was performed to compare our results. Results The combined median operating time for right and left colectomies was significantly higher in the NOSE group as compared with TAE group (260 vs. 150). There was no mortality in either group and no conversions to TAE in the NOSE group. No local metastasis or major iatrogenic injuries were reported at the time of retrieval. The results were comparable to those of a meta-analysis of randomized controlled trials. Conclusion The results of NOSE are comparable to those of TAEs. The absence of a minilaparotomy for specimen extraction may lead to a speedy recovery and better cosmesis.

Although laparoscopic colectomy shows superior short-term outcomes and similar oncologic outcomes in comparison to conventional open colectomy, incision-related complications have weakened its advantages. The natural orifice transluminal endoscopic surgery (NOTES) has been considered as the most perfect surgical approach. However, monumental technical hurdles have precluded widely adoption of this technique. As a transient mode, the natural orifice specimen extraction surgery (NOSES) emerges as the times require. Although it is accepted by surgeons for the treatment of colorectal cancer, there are still many disputes that need to be solved.

Abstract Objective: Healthcare workers (HCWs) are at risk of COVID-19 due to high levels of SARS-CoV-2 exposure. Thus, effective vaccines are needed. We performed a systematic literature review and meta-analysis on COVID-19 short-term vaccine effectiveness among HCWs. Methods: We searched PubMed, CINAHL, EMBASE, Cochrane Central Register of Controlled Trials, Scopus, and Web of Science from December 2019 to June 11, 2021, for studies evaluating vaccine effectiveness against symptomatic COVID-19 among HCWs. To meta-analyze the extracted data, we calculated the pooled diagnostic odds ratio (DOR) for COVID-19 between vaccinated and unvaccinated HCWs. Vaccine effectiveness was estimated as 100% × (1 − DOR). We also performed a stratified analysis for vaccine effectiveness by vaccination status: 1 dose and 2 doses of the vaccine. Results: We included 13 studies, including 173,742 HCWs evaluated for vaccine effectiveness in the meta-analysis. The vast majority (99.9%) of HCWs were vaccinated with the Pfizer/BioNTech COVID-19 mRNA vaccine. The pooled DOR for symptomatic COVID-19 among vaccinated HCWs was 0.072 (95% confidence interval [CI], 0.028–0.184) with an estimated vaccine effectiveness of 92.8% (95% CI, 81.6%–97.2%). In stratified analyses, the estimated vaccine effectiveness against symptomatic COVID-19 among HCWs who had received 1 dose of vaccine was 82.1% (95% CI, 46.1%–94.1%) and the vaccine effectiveness among HCWs who had received 2 doses was 93.5% (95% CI, 82.5%–97.6%). Conclusions: The COVID-19 mRNA vaccines are highly effective against symptomatic COVID-19, even with 1 dose. More observational studies are needed to evaluate the vaccine effectiveness of other COVID-19 vaccines, COVID-19 breakthrough after vaccination, and vaccine efficacy against new variants.
